I was hanging out in my garage with 3 other friends and we were smoking weed resin out of a steamroller and after I took my first hit, I started to get a sharp pain on the left side of my chest and it grew more severe with each passing moment. Then I realized how much I was over heating and I started to perspire a lot. So I stood up, so I could take deeper breaths then I fainted. I awoke a few seconds later with my friends around me laying my down. After I woke up it was extremely difficult to see and my asshole for some reason felt like it was burning and I had extreme sinus pressure and everything sounded muffled. I told my friends I wanted to go to the hospital and on our way there my vision slowly came back to me. And the pain had stopped. I drank a snapple and still felt weak walking on my own, but I could still manage. And i was just wondering what happened? Cause I haven't smoked only for a day, but before that I usually smoked daily and smoked alot. So anyone please let me know would be really appreciated.
